Zac Brown Band headlined the festival on both Saturday and Sunday night but handed My Morning Jacket headlining duties on Friday. Instead, the members of Zac Brown Band played a special set of covers, which included Stephen Stills’ “Love the One You’re With,” Steve Miller’s “Swingtown,” Ray LaMontagne’s “Trouble,” Widespread Panic’s “Ain’t Life Grand” and Ryan Adams’ “Oh, My Sweet Carolina.” Warren Haynes also joined the group for takes on Pink Floyd’s “Comfortably Numb” and Johnny Cash’s “Folsom Prison Blues.”
